家庭功能与大学生情绪表达性、孤独感的关系

通过问卷调查法和结构方程模型分析技术,探讨家庭功能与大学生情绪表达性、孤独感之间的关系,以及家庭功能的作用机制,即家庭功能能否通过情绪表达影响大学生孤独感。结果发现:(1)家庭功能对大学生情绪表达性、孤独感有显著预测作用,家庭亲密度或适应性水平高的大学生更倾向具有高的情绪表达性,更少的体验到亲情、爱情以及社交孤独感;(2)情绪表达性对大学生社交孤独感具有一定的预测作用,即大学生越乐于表达情绪,其社交孤独感就越少;(3)家庭功能既直接对社交孤独感产生影响,又通过情绪表达性间接影响社交孤独感,即情绪表达性在家庭功能与社交孤独感之间起部分中介作用。     

Capturing and evaluating blinks from video-based eyetrackers

Blinks are related to several emotional states, and the present report describes a simple, reliable way to measure blinks from the video stream of an eye obtained during eyetracking, where the source of the eye video is a video camera attached to a head-mounted eyetracker. Computer vision techniques are employed to determine the moments that a blink starts and ends, for the purpose of calculating blink frequency and duration. The video is first processed to show blocks of eyelid and pupil movements, and is then analyzed for blink starts and ends. The moment of a blink start is reported when the eyelid starts to move quickly, exceeding a predetermined threshold. The end of a blink arises when the pupil size increases by less than a separate threshold. We observed several different blink patterns from different subjects, and our algorithm was designed to work for all of these patterns. We evaluated our algorithm by manually measuring the true blinks of five different subjects while they were eyetracked. To test the sensitivity and specificity of the algorithm, we employed a series of threshold values to plot the receiver operating characteristic curves. Using the best thresholds, we achieved excellent sensitivity (>90 %) and specificity (>99 %) over the five subjects. Potential applications of this research include real-time, nonintrusive, continuous and automated measurements of mental workload and other emotional states related to blink rates and durations.

回鹘宗教史上的萨满巫术

萨满教在回鹘中流播时间长、范围广、影响大,以万物有灵论为思想基础,内容包括自然崇拜、图腾崇拜和祖先崇拜等方面。在 763 年摩尼教传入回鹘之前,该教一直享有国教的地位,巫师颇受回鹘统治者宠信。当萨满教的国教地位被摩尼教取代后,其影响并未消失,而是以改变了形式——巫术继续存在于回鹘社会中,以致影响到今日维吾尔族、裕固族的社会文化与习俗。     

A Brief Group Cognitive-Behavioral Program for the Prevention of Depressive Symptoms in Chinese College Students

Depression is a problem among college students in China. Yet the use of preventative group cognitive-behavioral (CB) intervention is rare. One hundred and eighty Chinese college students who were identified as being at risk for depression were randomly assigned to three groups: 1) a brief group cognitive–behavioral (CB) intervention, 2) a supportive group (SG) intervention, and 3) a wait-list control condition. The Zung Self-Rating Depression Scale (SDS), the Zung Self-Rating Anxiety Scale (SAS), and the Chinese College Student Adjustment Scale (CCSAS) were administered at pre-test, post-test, and six-month follow-up. Analysis of variance (ANOVA) conducted among the three groups revealed that the CB group demonstrated significantly less increase in measures of primary symptoms of anxiety and depression than the wait-list controls at post-test and six-month follow-up. The prevention effect of the SG group was significant only at the six-month follow-up. CB participants also showed significantly greater improvements in social adjustment than did SG participants and controls at the post-test and six-month follow-up.     

Team–Member Exchange and Work Engagement: Does Personality Make a Difference?

Purpose

Adopting a person–situation interactionist framework, this study examined the joint effects of employee personality (i.e., extraversion, neuroticism, and conscientiousness) and social exchange relationships with peers (i.e., team–member exchange; TMX) in predicting work engagement.

Methodology

This study is based on survey responses from 235 Chinese employees collected at two time points with 3 months in between. We conducted moderated regression analyses to test the hypotheses that employees higher in extraversion or conscientiousness or lower in neuroticism would demonstrate a stronger TMX–work engagement relation.

Findings

Results from this study showed that the three focal personality traits moderated the TMX–engagement relation simultaneously. Specifically, the positive TMX–engagement relation was stronger for employees with higher extraversion or lower neuroticism than that for their counterparts. Interestingly, the TMX–engagement relation was positive for employees lower in conscientiousness but negative for those higher in conscientiousness.

Implications

These findings support the notion that lateral social exchange relationships in the workplace (i.e., TMX) are an important antecedent of work engagement and, more importantly, their beneficial effects on work engagement are contingent on certain types and/or levels of personality traits.

Originality/Value

This study not only advances our understanding of presumed antecedents of work engagement but also opens a new door for future research on work engagement by highlighting the importance of a person–situation interactionist framework.     

Cross- and within-cultural variations in children's understanding of distance, time, and speed interrelationships: a follow-up study

A problem with interpretations of differences in mathematic achievement between students from Asian countries and those from the United States is the seemingly implicit assumption of the cultural homogeneity of Asian societies. Researchers rarely measure the effects of variables within cultures that are hypothesized to be related to differences across cultures. In the present study, the authors examined the effects of socioeconomic status (SES) and quality of instruction on Chinese students' (1st, 3rd, and 5th grades) understanding of distance, time, and speed. The results indicated that (a) low SES in China can impede the development of children's mathematical cognition and (b) higher SES does not guarantee better performance. The implication is that the gap in mathematical performance between socioeconomically advantaged and disadvantaged children can be narrowed or even eliminated through instructional practices that focus on the systematic training of children's mathematical thinking.     

Determinants of justification and self-control

The authors propose that people use 2 routes in justifying self-gratification: 1st through hard work or excellence (entitlement) and the 2nd through the attainment of vices without depleting income. This framework was tested using real tasks and choices adopted from prior research on self-control. The results indicate that (a) higher effort and (bogus) excellence feedback increase preferences for vice rewards, but these effects are reversed or attenuated when the interchangeability of effort and income is implied; (b) willingness to pay in effort is greater for vices than virtues, but willingness to pay in income is higher for virtues; and (c) these effects are magnified among individuals with stronger (chronic or manipulated) guilt. The authors discuss the ability of the justification routes to explain the findings of prior self-control research.     

Modeling of 1-3 piezoelectric composites operating in thickness-stretch vibration mode

For bulk piezoelectric ceramics plates, the fundamental thickness-stretch (TSt) waves are always coupled to the in-plane extension waves and the symmetric thickness-shear waves. The occurrence of these spurious modes in bulk piezoelectric ceramics plates is undesirable as it may interfere with the operation of transducers. 1–3 piezoelectric composites are promising candidates to suppress the spurious modes mentioned above. However, theoretical modelling of multiphase ceramic composite objects is very complex. In this study, a simple analytical TSt vibration model is constructed from three-dimensional equations of linear piezoelectricity. The mechanical damping is considered in the model by introducing a complex elastic constant. The performance of 1–3 piezoelectric composites is analysed and the electrical impedance results from theoretical and experimental analysis are compared. The results show that there is excellent agreement between the experimental electrical impedance and that obtained by the theoretical TSt vibration analysis. This indicates that 1–3 piezoelectric composites can be operated in a nearly pure TSt vibration mode near the fundamental resonance. The analytical model we present is valid for analysing 1–3 piezoelectric composites plates with large aspect ratios quickly and efficiently.     

Multidimensional scaling reveals two dimensions of thermal pain

The Individual Differences Scaling (INDSCAL) model of multidimensional scaling was used to explore the dimensions of thermal pain. The observers made 66 similarity judgments to all pairs of 12 different thermal stimulus intensities ranging from zero to noxious. Analysis of the data revealed a two-dimensional group stimulus space. The major dimension ordered the stimuli with respect to their intensity. This quantitative, strength-of-sensation dimension may be interpreted as indicating how weak or strong a stimulus feels, apart from any secondary qualities of warmth or pain. The second dimension was related to the qualitative aspects of the stimuli. This bipolar dimension contained two attributes: a pain attribute ranging from just detectable warmth to painful, and a warm-hot attribute running from just detectable warmth to hot. This study demonstrates the utility of the INDSCAL approach to the understanding of pain and offers a new technique for answering the age-old question concerning the number and qualities of the dimensions underlying the pain experience.
